WordPress Training: Publishing your post at a later date
Sometimes you might want to write a post and have it all set up to post in, say, a week or a month’s time, rather than right away. The good news is that you can do that without having to come back and publish it manually, later on.
So, from the main writing view, once you’re ready, just click here on edit next to the part of the publish panel says “Publish Immediately”. Now dial in the month, Tap in the date, year and time that you’d like the post to go live, and click “OK”. Remember, unless your time zone is UTC you’ll probably want to change that in your settings General menu. Now hit publish, and don’t worry the post won’t be seen until the date you’ve told WordPress to publish it.
